Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Summary

Physical Characteristics

Ephedra gerardiana is an evergreen Shrub growing to 0.6 m (2ft) by 2 m (6ft 7in). It is hardy to zone (UK) 7. It is in leaf all year. The species is dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required). . The plant is not self-fertile. Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil and can tolerate drought.

Members of this genus contain various medicinally active alkaloids (but notably ephedrine) and they are widely used in preparations for the treatment of asthma and catarrh[238]. Ephedrine acts promptly to reduce swellings of the mucous membranes and has antispasmodic properties, thus making it valuable in the treatment of asthma[4]. This species contains between 0.28 and 2.79 alkaloids[240]. The whole plant can be used at much lower concentrations than the isolated constituents - unlike using the isolated ephedrine, using the whole plant rarely gives rise to side-effects[254]. The plant also has antiviral effects, particularly against influenza[238]. The stems are a pungent, bitter, warm herb that dilates the bronchial vessels whilst stimulating the heart and central nervous system[238]. The stems are also diaphoretic. diuretic and vasodilator[4, 61, 165, 238]. They are used internally in the treatment of asthma, hay fever and allergic complaints[238]. They are also combined with a number of other herbs and used in treating a wide range of complaints238]. This herb should be used with great caution, preferably under the supervision of a qualified practitioner[238]. It should not be prescribed to patients who are taking monoamine oxidase inhibitors, or suffering from high blood pressure, hyperthyroidism or glaucoma[238]. Ephedrine is seen as a performance-boosting herb and, as such, is a forbidden substance in many sporting events such as athletics[K]. The stems are used in Tibetan medicine, where they are considered to have a bitter taste and a cooling potency[241]. Febrifuge, tonic and vulnerary, they are used in the treatment of severe bleeding and chronic fevers[241]. A decoction of the stems and roots is used in Russia to treat rheumatism and syphilis[243]. The stems can be harvested at any time of the year and are dried for later use[238]. The juice of the berries is used to treat respiratory affections[243].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

The wood is very close grained[158]. Too small for commercial exploitation, though it is used locally for fuel[146]. A good ground cover plant for dry soils[188]. Plants should be spaced about 60cm apart each way[208].

Special Uses

Cultivation details

Requires a well-drained loamy soil and a sunny position[11]. Established plants are drought resistant and are also lime tolerant[200]. Plants are hardy to about -15°c[200]. Dioecious. Male and female plants must be grown if seed is required.

The PFAF Bookshop

Plants For A Future have a number of books available in paperback and digital form. Book titles include Edible Plants, Edible Perennials, Edible Trees, and Woodland Gardening. Our new book to be released soon is Edible Shrubs.

Propagation

Seed - best sown as soon as it is ripe in the autumn in a greenhouse[200]. It can also be sown in spring in a greenhouse in a sandy compost[K]. Prick out the seedlings into individual pots as soon as they are large enough to handle and grow them on for at least their first winter in a greenhouse. Plant out in the spring or early summer after the last expected frosts and give some protection in their first winter[K]. Division in spring or autumn[238]. Layering.
